Title: Improvements in and relating to the cooling of the pistons of internal combustion engines
IPC: F01P1/04
Filed: 1919-05-08
Abstract: 148,011. Sage & Co., F., and Forsyth, A. G. May 8, 1919. Pistons, cooling.-Relates to the cooling of the pistons of two-stroke internal-combustion engines of the type in which a supercharge is forced into the cylinder after the exhaust ports have been closed. The piston shown has three chambers 7, 8, 9, through which the charge is supplied from a pipe 6, displacing the products through ports 18 to the exhaust pipe 19. Passages 15, 17 convey the charge from the piston channels to the cylinder. After the piston has risen slightly and closed the channels 7, 9, and the exhaust ports 18, a supercharge is supplied through the deeper channel 8, past the non-return valve 20, and through the passages 21.

Filed: 1939-04-15
Abstract: 527,593. Moving signs. DEAL, H. P. April 15, 1939, No. 11535. [Classes 3 (i) and 3 (ii)] A plurality of facetted reflectors 10 are loosely mounted each in a cavity 7 slightly larger than the reflector and having a rear extension 9 into which the conical back. of the reflector projects sufficiently to prevent the reflector moving into an ineffective position, the reflectors being enclosed by a transparent cover 15 of celluloid &c. The device is carried by a vehicle or other vibrating body, such as one actuated by wind, so that the reflectors are shaken and scintillate. The transparent retaining cover 15, or the conical rear reflecting surface of the reflector, or the body of the reflector itself, may be coloured. The reflectors may be arranged as lettering &c. to form a sign, or may be attached to the back of a glove for signalling, or on a strap for personal wear, or on an attache case.

Title: Method of forming a splined member by hobbing
IPC: B23F15/00
Filed: 1933-04-21
Abstract: 410,603. Hobbing splines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Barber- Colman Co.; River Street, Rockford, Illinois, U.S.A.) April 21, 1933, No. 11732. [Class 83 (iii).] In a method of hobbing a splined member 10 a hob 15 is located with its axis inclined to a perpendicular to the work axis 10<1> in accordance with the inclination of the hob thread and is fed transversely across the work while the hob and work are continuously rotated in timed relation. The sides of each key 12 on the work are parallel so that the sides of a groove 13 converge inwardly, the roots a of the groove being tapered longitudinally. Preferably clearance grooves 14 are formed at the longitudinal margins of the roots a. The hob has a cylindrical body with one or more threads 18 intersected by longitudinal gashes perpendicular to the threads to form teeth having relieved tops C, each thread being tapered from end to end of the body. The tops of the teeth are axially inclined in accordance with the taper. Lugs 21 may be provided to cut the clearance grooves 14 but if these are not required, the lugs may be dispensed with. The profile of the hob threads depends on the form to be generated. In operation, the hob is positioned as shown in Fig. 6, with the large end adjacent the work, the inclination being such as to bring the hob threads at the point of operation parallel to the work axis. The hob and work are rotated in timed relation and the hob is fed diagonally across the work in the direction n so that the large end of the hob cuts grooves of maximum depth at the point g while the small end subsequently engages the work at the point g<1>. The component h of the hob movement is preferably constant while the component i is varied according to the required length of the work grooves, being such that the intercept on a line parallel to the work axis made by lines passing through the ends of the hob and drawn in the direction of the feed, is equal to the required groove length f. Fig. 6, shows a triple-threaded hob, but in some cases a single thread hob may be used. In a modification, Fig. 7, the hob may be arranged so that when it is in correct angular relation to the work piece its projected length f on the work axis is equal to the groove length required. In this case the hob is fed perpendicularly to the work axis between the positions shown. Specification 410,604 is referred to.

Title: Improvements in or relating to combined axial-flow and centrifugal compressors
IPC: F04D27/02
Filed: 1944-06-21
Abstract: 580,458. Compressors. ESCHER WYSS MASCHINENFABRIKEN AKT.-GES. June 21, 1944, No. 11793. Convention date, June 22, 1943. [Class 110 (i)] In a compressor having axial flow low pressure stages 1 and centrifugal high-pressure stages 5, surging at low outputs is prevented by withdrawing some of the compressed fluid between the high and low pressure parts. A branch pipe 6 draws off fluid from the delivery of a connecting member 3 and delivers it to the open air or to the suction side of the compressor through a cut-off valve 7 which is controlled automati-' cally in dependence on the pressure p2 prevailing at the delivery end of the low pressure part 1. The connecting member 3 may be a pipe but is preferably an intercooler as shown. When vapours are being compressed, condensate may be injected into the branch pipe 6 to lower the temperature of the vapour. The high and low pressure parts of the compressor may be housed in a common casing in which case the intercooler or other connecting member can be made integral with the casing.

Patent GB-1602218-A (GB)
Title: Process for purifying an off-gas containing sulphur dioxide
IPC: B01D53/77
Filed: 1978-03-28
Abstract: In a process for purifying a sulphur dioxide-containing exhaust gas by passing the exhaust gas into a sulphite-ion-forming aqueous solution, oxygen is fed to the aqueous solution. As catalyst, activated charcoal is added which was heated to red heat at a temperature above 1000 DEG C in a reducing or inert atmosphere and cooled. In this process, the process steps required for eliminating the toxic activity of sulphur dioxide are substantially reduced. The process proceeds with the use of active compounds which do not have to be regenerated or which only need to be regenerated to a very limited extent.

Title: Stock box for a paper-making machine or the like

Abstract: 1,142,916. Papermaking. J. M. VOITH G.m.b.H. 15 March, 1967 [16 March, 1966], No. 12152/67. Heading D2A. In a headbox that is isolated from the atmosphere and has a feed pipe for supplying stock to the headbox, a slice for supplying stock to the machine, an overflow weir extending across the full width of the headbox, a pipe for removing fluid that has flowed over the weir and a connection between the space above the stock to an air pump to create a cushion of air above the stock, the outflow pipe has a constriction so that the fluid level in a section of the pipe depends on the rate of flow over the weir, and a wall of the pipe section which is not horizontal at the fluid surface has a secondary outlet at the level of the fluid surface, the cross-section of the outlet being smaller than that of the pipe. As shown, the headbox 2 receives stock from a pipe 4, and emits it from the slice 5. An air-pump 9 maintains pressure or vacuum in the space above the stock surface 3 by means of pipes 12 and 13 and three-way valves 10 and 11. A channel 16 has a weir edge .17 and leads to an outlet pipe 19 and a white-water basin 20 under the machine, 29 and 30 are the breastroll and wire of a Fourdrinier machine. Flow through the pipe 19 is constricted by a valve 23, to maintain a mean fluid surface 26. A second pipe 27 passes into or through the pipe 19 and communicates with it. by a tapered vertical slot 28. As the rate of flow over the weir rises or falls, so does the level 26. This causes a fall or rise in the rate of escape of air through the slot 28, so altering the pressure in the air space above the stock to restore the fluid level to its former position. In a modification (Figs. 2 and 3, not shown), the height and cross-sectional area of the opening 28 are both variable.
